iphone – iOS 6上的Cocos2D 2.0截图

+(UIImage*) screenshotWithStartNode:(CCNode*)startNode
{
    [CCDirector sharedDirector].nextDeltaTimeZero = YES;

    CGSize winSize = [CCDirector sharedDirector].winSize;
    CCRenderTexture* rtx = 
    [CCRenderTexture renderTextureWithWidth:winSize.width 
                                 height:winSize.height];
    [rtx begin];
    [startNode visit];
    [rtx end];

    return [rtx getUIImage];
}

你可以这样称呼它

CCScene *scene = [[CCDirector sharedDirector] runningScene];
CCNode *n = [scene.children objectATindex:0];
UIImage *img = [AppController screenshotWithStartNode:n];
